Java: How to implement duplicate key for a HashMap?

+1 vote
217 views

Example
Map data = new HashMap();
data.put("a","America");
data.put("a","Africa");
data.put("b","Bangladesh");

Need to have both "America" and "Africa" as value against key "a". Is there any mechanism to achieve this scenario.
